Oops, I forgot about the part about switching the filters. A typical
exposure might be 25 seconds with a #4.5 filter then turn off the light,
replace it with a 1/2 filter, and turn the light back on for a short time,
like 3 seconds. It's supposed to be most effective with really thin
negatives. Putting two filters in at the some time would be totally
pointless...
